Embodiment Construction
[0015] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0016] Such as figure 1 and figure 2 As shown, a kind of space-based detection reference calibration method based on high-bandwidth gyro measurement of the present invention comprises the following steps:
[0017] Step 1: Measure the relative change of the detection reference in real time, and reduce the thermal deformation transmission path between the detection reference on the satellite and the satellite attitude reference.
[0018] Step 2, installing a high-bandwidth gyroscope 1 on the back of the scanning mirror 3 for measuring the normal vector of the scanning mirror in the inertial coordinate system.
[0019] Step 3: Install the fiber optic gyroscope 2 on the base of the camera light-mechanical body 4 close to the detector, and install the star sensor on the base near the detec...
